1. Bad Couple
I thought Bad Couple fit the emotions and the story itself so well - just hearing the music itself could bring tears to my eyes; the melody and singers were beautiful and delicate, just like the characters in the story. Also, there is not one OST on that soundtrack that I didn't love. So, even though it isn't the most well-known soundtrack, I think it's the best.
